I Googled the Real Book 6th edition Bb and got a plethera of sites to download the PDF file, however, each one seems to have have malcious virus attached to it. I have no problem with paying for it but Amazon only sells the book and I don't want to have to have to convert it to PDF by scanning. Any ideas?

The best idea is not to download stuff from those sites. If you have the physical book scan it, that's really all the help we can give with respect to that. We don't provide content, that's on you, we just provide a tool to manage it.
